Note that the scrolls will damage your character on use; fire resistance is advisable. A single explosion of an enemy will cause roughly 100 damage so be careful if using the scroll with multiple enemies nearby as you can take your health down very quickly if you have multiple enemies around. It is also advised to make any Followers wait well enough away from you as they may become hostile if they get close to you while you are wearing the Flame Cloak.

After completing the quest J'Zargo will reward you with gold and offer his services as a follower. Any Scrolls unused during the quest are yours to keep.
